I saw somewhere in this forum where seafoam was added to the transmission and then the car was driven a little while to flush out the crud. Has anyone done this? it sounds like you might damage something. I was going to replace the solenoid s1 because of the 750 error and the flashing arrow of doom....

How are the trans parts solenoids holding up? They are sooo cheap. They look ok I guess. I also purchased them because I can't get the right ones from volvo OR FCP. I didn't start the job yet...still working up courage. makotransmissionparts.com sells a gasket for $5 making the job a little easier.....
